Troubleshooting

1. Why does the Megapixel PoE Network Camera work locally but not externally?

‧ This might be caused by network firewall protection. The setting of the firewall may need to be

changed in order for the Megapixel PoE Network Camera to be accessible outside of your local LAN.

Check with the Network Administrator for your network.

‧ Make sure that your Megapixel PoE Network Camera isn't conflicting with any Web server you may

have running on your network.

‧ The default router setting might be a possible reason. Check that the configuration of the router

settings allows the Megapixel PoE Network Camera to be accessed outside of your local LAN.

2. Noisy images occur. How can I solve the problem?

The video images might be noisy if the Megapixel PoE Network Camera is used in a very low light

environment. To solve this issue you need more lighting.

3. The images appear to be of poor quality, how can I improve the image quality?

‧ Make sure that your computer's display properties are set above 256 colors. Using 16 or 256

colors on your computer will produce dithering artifacts in the image, making the image appear to

be of poor quality.

Advanced > Image Setup section of the Web management you need to adjust the image related

parameters such as brightness, white balance and power line frequency for fluorescent light.

4. Can the Megapixel PoE Network Camera be used outdoors?

The Megapixel PoE Network Camera is not weatherproof. It needs to be equipped with a

weatherproof case for outdoor use but it is not recommended.

5. Can the network camera be installed and work if a firewall exists on the network?

If a firewall exists on the network, port 80 is open for ordinary data communication. The

DCS-3110 uses port 554 for RTSP streaming. These ports – or the ports that you specified in the

Setup Tab in the Configuration screen – need to be opened on the firewall.

6. Why am I unable to access the Megapixel PoE Network Camera from a web browser?

If a router or firewall is used on the network, the correct ports for the DCS-3110 may not be

configured on the router or firewall. To correct the problem, you need to determine if the

DCS-3110 is behind a router or firewall and if the router or firewall is properly configured for the

ports the DCS-3110 is using. Refer to Page 28 for help in opening the correct ports on a router or

firewall for use with the DCS-3110. Other possible problems might be due to the network cable.

Try replacing your network cable. Test the network interface of the product by connecting a local

computer to the unit, utilizing an Ethernet crossover cable. If the problem is not solved the

Megapixel PoE Network Camera might be faulty.

7. What is the maximum number of users that can access DCS-3110 simultaneously?

The maximum number of users that can log onto the Megapixel PoE Network Camera at the

same time is 10. Please keep in mind the overall performance of the transmission speed will be

reduced if many users have logged on to the camera simultaneously.
